RECORDING-GAGE.

To all whom it may concern:

Be it known that I, WILLIAM YoUNe, a 1 citizen of the United States,residing at Uled'i, in the county of Fayette'and State of ennsylvania,have invented certain new and useful Improvements in Recording- Gages;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. I

Thisinvention relates to improvements in recording gages.

The object of the invention is to provide a I gage of this characteradapted to be connected to any form of engine or motor, wherebthe'location, time and speed of the same will be correctly recorded.

With these and other objects inview, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out in theappended In the accompanying drawing, Figure 1 is a side view of a gageconstructed in accordance with the invention; Fig. 2 is a top plan viewof the same; Fig. 3 is a detail sectional side view of a modified formof the gage; Fig. 5 is a top plan view .of the same; and Fig. 6 is adetail view of the recordin finger used in connection with the gage. ig.7 vis a rear elevation of a part of the device shown in Figs. 4, '5 and6. Y

Referring more particularly to Figs. 1, 2 and 3 of the drawing, 1denotes a-b ase or support having on itsrear side adjacent to one end,suitable bearings, 2, in which is revbly mounted an operating shaft 3.On the shaft, 3, is a sprocket gear, 4, with which is engaged a sprocketchain, 5, adapted to connect with a movin part of the engine or motor tobe gagedj n the shaft, 3, is also Specification of Letters Patent.Application filed August 10,

i the bar. 1

arranged a worm, 6, which engages-a worm gear, 7, fixed on a stub shaft,8, mounted in the base. The'op osite end of the shaft 8 projects throught e base and has mounted thereon a disk, 9, having on its outer face aspirally formed thread, 10. Slidably mounted on the base, 1, is afinger-operating bar, 12, in one end of. which is formed a longitutheend of the shaft, 8, as

shown, and in which is adjustably secured a pin, 14, the

Inner end of which isv adapted to engage the 1 Patentediazf.26,1909.190s. Seria1No.447,815.

spiral thread 10 in the disk 9 whereby the movement of the disk iscommunicated. to the finger-operating bar, 12. The pin '14'is rovidedadjacent to its inner endwith a fiead, 15, which engages the inner sideof the bar, 12, and on its outer end the pin 'is threaded to receive aclamping nut, 1'6, which is adapted to be screwed up gagement with theouter sidebar, thereby clamping the pin in its ad'usted position on Theoperating ar, 12, is preferably jointed midway between its ends,- asshown at 17, and the ortion, 18, of the same is reduced and slidab yeng-a ed with hearing brackets, 19, arranged on t e base plate 1. Thereduced portion, 18, of the o crating-bar has fixedly connected theretoetween the bearing brackets, 19, a recording arm, 20, 4

other suitable recording device, 21. The recording pencil in the outerend of the finger 20 is operatively engagedwith a recordin dial, 22,which. is divided into annular an radial division lines, said radiallines corres onding to the time divisions of a clock dia while theannular lines are rovided to indicate speed and location. T e dial, 22,is suitably connected to a clock mechanism 22 whereby the dial isoperated.

From the foregoing description, it will be seen that as the operatingbar. 12 isreciprocated back and forth by its connections with theoperating part of the engine or motor, the recording ar carrying thepencil will move the latter back'and forth across the dial, while thesame is being revolved. by the clock mechanism so that the lines drawnon the dial by the recording pencil will correctl indicate the time,speed and location of the movements of the en ine or motor.

In Figs. 4 and 5 of t e drawings is shown-a slightly modifiedarrangement of the operatingmechanism. The gage in this instance isshown as provided with a base, 23, bearings, 24, an o'perating'shaft,25, having a sprocket gear, 26, and chain, 27, whereby said shaft isoperatively connected to an engine or motor. The shaft, 25, is providedwith a worm, 28, to engage a worm ear, 29, on a stub shaft, 29, mounted1n and projecting through the base, 23. On the opposite end of theshaft, 29, is a fixedly mounted disk, 30, which differs from the grooveddisk 9 of the first form of gage. The disk 30 has formed therein aradially disposed slot, 30*,

' connected to ether,

with which is engaged a wrist pin, 31, secured to the outer end of anoperating bar, 32, whereby'said bar is reciprocated. The bar, 32, isformed in two sections hingedly as at 33 and the ortion, 34, of t e baris slidabiy mounted in bearing brackets, as shown. The art, 34, of theoperating bar, 32, has fixe y connected thereto a recording arm, 36,,which carries a pencil or other suitable recording device adapted to beengaged with a dial, 37, which is operatively connected to a clockmechanism, 38, suitably mounted on the base, 23, of the gage. 0 erationof this recording arm and dial is t e same as described in connectionwith the other form of gage. o

The slot, 30 in the, disk,-30, provides for the adjustable connection ofthe outer end of 2 0.

the operatinglbar, whereby the stroke of the latter and t e movement ofthe recording arm'may be regulated. The slot in the operatin ar 12 oithefirst form of gage also provi es for the adiustment ofthe operating pin,14', whereby t e stroke of the bar 12 is regulated. The recording armsof both forms of the gage are-preferably in the form of a straight bar,39, plvotally mounted at its inner end in a bearing bracket, 40, securedto the operatin bar. The inner end of the bar, 39, is provi ed with aright-angularly projecting weighted arm, 41,- whereb the pencil on theouter end of the bar is he d in operative engagement with the disk.

A gage constructed as herein shown and described may be connected withany suitable part of an engine or motor, and the speed, time andlocation of the same accurately recorded on the dial.

From the foregoing description, taken in connection with theaccompanying drawing, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the term, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined by theappended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters-Patent, is:

1. In a. age of the character described, a clock, a dia supportoperatively connected to 35, secured to the base, 23,

The

2. In a gage of the character described, a clock, a dial supportoperatively connected to the clock, a recordin arm having a recordingpoint to en age a dia on said support, an operatingpsha 't, an operatingdisk mounted on the shaft and having a spiral thread formed thereon, astub promotion on said shaft, a slotted operating bar connected to saidarm and engaged wit said stub projection on the shaft, a inhaving anadjustable connection with sai bar and adapted to engage the spiralthread on said disk whereby the bar is moved to actuate the recordingarm, a driving mechanism connected to said operating disk, and means toconnect said driving mechanism to the moving part of an engine or motor.

3. In a gage oi the character described, a base, a clock mounted on saidbase, a dial support operatively connected to said clock, said supportcarrying a dial having thereon annular and radially disposed divisionlines, a recording arm having a recording point to engage said dial, anoperating bar slidably mounted on said base and operatively connected tosaid recording arm, said bar having formed therein a slot, a shaftmounted in said base adapted to enter the slot to guide of said shaft, aspira thread on said disk, a pin adjustably mounted in the slot of said0 crating bar and adapted to engage the t read on said disk, a worm gearon the opposite end of said disk Sil5.fi3,'2t11d. means to operativelyconnect said driving shaft with a moving part of an engine or motor,substantialiy as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
